It was generally fine beforehand, but now it's just terrible. It randomly closes down, goes back a step that you've already completed and subtracts goals you've completed. I've reported so many times where my answer was correct and they told me it was wrong, and they send a joyful email confirming that my assertion was accepted - they should be ashamed not joyful. Further, the customer service is worthless. Not going to use it anymore.
